Patent GB-490199-A (GB)
Abstract: 490,199. Calculating-apparatus. SOC. ANON. OFFICINE DI VILLAR PEROSA, and BERIA, B. March 4, 1938, No. 6802. Convention date, March 4, 1937. Addition to 470,265. [Class 106 (i)] In a totalizer for calculating- machines provided with a transfer mechanism as described in the parent Specification the transfer actuating members or sleeves are each provided with a collar which is non-rotatable thereon but movable longitudinally thereon and each is formed with a projection or cam in the path of movement of a similar projection or cam on the side of the numeral wheel of the next lower denomination whereby the sleeve is moved longitudinally to transfer operating position. As shown in Figs. 1 to 3, the numeral wheels 4 are mounted loosely on a shaft 2, and the transfer sleeves 5 are slidably keyed on a shaft 3. The numeral wheels are formed with teeth 6 engaged by the differential actuating mechanism (not shown), and with a flange 4a providing a recess for the strips 16b of a sheet metal member 16 to space the wheels. The member 16 is secured by screws 17 to the pivot 13 of the totalizer casing. The shaft 3 carries a key 18 with teeth 18a, adapted to engage grooves 19 in the sleeves 5. Each transfer sleeve is provided with a collar 25 mounted for longitudinal movement with the sleeve and rotatable with respect thereto; angular movement of the collar 25 is prevented by abutments 27, 28 thereon resting on parts of the member 16. Each collar has a cam 29 in the path of movement of a cam 30 on the side of the numeral wheel of lower denomination. At transfer the cam 30 by engagement with the cam 29 displaces the sleeve 5 so that when the shaft 3 is rotated the projections 18a of the key 18 cause this sleeve to be rotated and a transfer tooth 31 thereon advances the next higher numeral wheel. After the transfer operation a cam 32 on the sleeve engages a lug 16d on the member 16 to restore the sleeve to normal position. Rotation of the shaft 3 is derived from a uni-directional coupling 22 the driving pinion 21 of which gears with a pinion 20 secured to a toothed wheel 14 keyed to the shaft 2 and driven by a gear 11 of the operating mechanism. To zeroize the numeral wheels a member 9 is operated to displace a key 7 on the shaft 2 so as to bring projections 7a thereon into alignment with pick up projections 8 on the numeral wheels. Rotation of the shaft 2 effects the zeroizing operation as described in Specification 471,765.

Abstract: 1374304 Transistor storage cells NIPPON TELEGRAPH & TELEPHONE PUBLIC CORP 5 Nov 1971 [11 Aug 1971] 51509/71 Heading H3T [Also in Division G4] A shift register uses carrier storage in semiconductors. Each of a plurality of stages U1, U2, U3 constituting a shift register contains a transistor T1 and two diodes D1, D2 (Fig. 6) or two transistors T1, T2 (Fig. 4) wherein T1 collector and either T2 collector or D1 cathode are alternately energized by separate conductors 1, 2. If a binary signal (B, Fig. 5, not shown) at the input 4 forward biases T1 collector-base function when line 1 is relatively negative, minority carriers are stored there, and these subsequently cause T1 to conduct when line 1 goes high and line 2 low, so that T2 collectorbase junction, or D1, is made to store carriers. Thus information is shifted from T1 to T2 or to D1 and similar action continues along the register. Read out from different stages of the Fig. 4, register is achieved either (Fig. 8, not shown) by connecting the collector and base of T1, T2 the collector and base of a respective extra transistor (T5, T6) whose emitter drives a load such as a diode or a resistor.

Abstract: 1,126,673. Crimping and tensioning yarns. BURKLAND LABORATORIES Inc. 7 Dec., 1965 [21 Jan., 1965], No. 51814/65. Headings DID, D1F and D1W. In a method of bulking and/or texturing synthetic yarn to produce crimp in each filament thereof, a continuously running yarn is passed over a vibrating head whereby mechanical shock is applied against the filaments in a non-longitudinal direction and at a rate which is at least sonic. The shock comprises recurring vibrations having "high acceleration rates but low displacement amplitudes". Heat produced incidently in the process may assist the (non-torque) crimping action. The vibrations may be applied intermittently so that the final yarn has alternate bulked and non-bulked longitudinal portions. As shown, yarn Y from spindle 10 passes through a guide 11, mechanism comprising a block 13a reciprocated through a sleeve 14 and urged towards a block 12 by a spring 15 calibrated to provide a predetermined drag upon the yarn, over the top surface of a crimping head 4, between pinch rolls 16, 17, whereafter tension is relaxed, to allow yarn to assume a bulked state B and hang in a loose caternary K, before passing through an electric heater 22, to enhance the bulking effect, thence to wind-up spool 20. A generator I delivering an ultrasonic, undulating, electrical output drives a crystal transducer 2 which drives a mechanical motion transforming column 3 supporting the crimping head. A rotary drum switch 5 alternately opens and closes (or may be set to maintain) the circuit between generator and transducer to modulate the amplitude of the head vibration at a relatively slow rate or vary the amplitude. Multiple ends of yarn may be treated by simultaneous passage over the same crimping head. The mode and form of vibration (and consequent bulking effects thereof) may be determined by the shape of the upper surface of the crimping head which may be knife-edged, rounded (especially at the edges) doubly recessed or concave, Figs. 3 and 4 (not shown). A modified head, Fig. 5 (not shown) comprises two complementary, serpentinely-surfaced blocks in the air cushion between which the travelling yarn is alternately clamped and released.
